The converter is plug-and-play without any jumper settingsThe converter is applicable for all the existing communication software and interface hardware withoutany software modifications for the previous working mechanism based on RS-232.A reliable and stable point-to-point and point-tomultipoint communication can be ensured by HighTek HK-5108 photoelectric isolation interface converter. For point-tomultipointcommunication, as many as 128 interface facilities of RS-422 or RS-485 standard can be connected to each converter, and a high data transmission rate of 300-115.2KBPS can be achieved. Power indicator light and data traffic indicator light are also available with the converter for malfunction indication. Two conversioncommunication modes including RS-232 to RS-422 and RS-232 to RS-485 are supported.
